Impact Study of Bend Tube on Bullet Initial Disturbance under the Action of Gravity


Article Preview

In order to study the influence of bend tube on firing accuracy due to gravity, a finite element model of sniper rifle, only considering the interaction between bullet and tube, was established based on nonlinear finite element method. The initial disturbance of bullet was taken as a measuring standard of firing accuracy. The model was used to simulate the launch process of sniper rifle under the condition of gravity static equilibrium in the method of the mixing calculation which had advantages of both dynamic explicit algorithm and static implicit algorithm. The simulation results show that vertical stiffness increases due to gravity and then the instantaneous velocity and attitude of bullet are largely influenced. Bending tube has a great influence on bullet motion.
